OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 394,245, dated December11, 1888.

Application filed April 29, 1887. Serial No. 236,592. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN CARNES, a citizen of the United States, and aresident ofLima, in the county of Allen and State of Ohio, have inventeda new and useful Oil-Burner, of which the followin is a specification.

My invention is an improved oil-burner 'for burning crude or refinedoil, without steam, in heating or cooking stoves.

Figure 1 is a perspective view of burner, with the stove in section.Fig. 2 is a plan view of the burner. Fig. 3 is a central verticalsection of the burner.

A is my burner, consisting of a hollow cone constructed with a spiralgroove, said cone being provided with side openings for the passage ofair to the flame.

B is an oil-pipe, through which oil is c011- ducted up through thecenter of the spiral to the top of the groove; C, the spiral groove; I,a stove; H, an air-hole above the burner or grate; K, an exit for smokebelow the burner.

Between the coils of the spiral groove are air-spaces L.

The operation of my device is as follows; Oil is admitted through pipe Bfrom a tank situate in any convenient position, and drops out the toponto the declining spiral groove,

where it is set fire to. As the oil spreads over the concave surface andfollows around the turns of. the groove while burning, it soon heats theburner until the oil that follows is turned to gas as it flows over theheated surface and is consumed. It is a well-known fact that cold airadmitted to a stove has a tendency to drop to the bottom of the stoveand stay there until heated as hot as the smoke and flame, while theheated gases seek the top and remain there or escape out the chimney. Totake advantage of this fact, I locate my cold-air supply or draft at thetop and exhaust or smoke escape at the bottom of the stove. By thismeans the heavier and colder airs are drawn off from the bottom,whilethe gases remain in the top of the stove, where I also locate my burnerin the midst of them and consume them, instead of letting them escapefrom above the fire, as is usual. By this means I get a perfect draft.The cold air is carried oft at the bottom, while the lighter gases andsmoke are consumed by the fire above. By this means it will be readilyseen that I not only prevent the escape of much of the inflammable gasesusuallywasted, but provide a practical smoke-consumer besides.

'hat I claim is- 1. An oil-burner consisting of a hollow coneconstructed with a surrounding spiral groove, said cone being providedwith side openings for the passage of air, as and for the purpose setforth.

2. The combination, with the stove having an air-entrance at the top andsmoke-exit near the bottom, of the hollow cone construeted with asurrounding spiral groove, having side openings for passage of air, andlocated in the top of the stove, beneath the air-entrance, as and forthe purpose set forth.

JOHN CARNES.
